← ScienceWhich parameter alters when a fluid exceeds Reynolds number?
A)Flow regime transitions into turbulence✓
B)Viscosity increases linearly with velocity
C)Surface tension reaches zero value
D)Fluid density changes substantially
💡 Explanation
Entering turbulence occurs because the inertial forces overwhelm viscous forces, promoting chaotic eddy formation; therefore the flow becomes turbulent rather than remaining laminar, because viscosity maintains order at lower numbers.
